Can metropolol replace bisoprolol temporarily?

38m 230lbs So, I unfortunately forgot the holiday on Monday and missed the pharmacy before going away. I am going to run out of bisoprolol I take for tachycardia/hbp. The more troubling of the two is the heart rate for me, I missed a dose once since being on it and I can feel my heart pounding in my chest. My wife takes metropolol to lower heart rate after having a heart attack years ago. Can I temporarily take metropolol to control the heart rate for a day or two until getting home? I realize medication is not meant to be shared, not to take someone's meds etc. I wouldn't even consider it except for the extremely uncomfortable feeling when my heart races and beats heavy now..
